Description

Technical Field

[0001] This utility model relates to the field of cryogenic winch technology, specifically to a cryogenic winch with automatic lubrication. Background Technology

[0002] As oil exploration continues, more and more underground oil is being discovered in places with consistently low temperatures. In order to adapt to such environments, the winches used must be able to withstand low temperatures, and there are many different types of low-temperature winches on the market.

[0003] However, a utility model patent with authorization announcement number CN218860228U discloses a low-temperature resistant winch that is easy to maintain. The winch includes a base, with support frames fixedly connected to both sides of the top center of the base, upright plates fixedly connected to both sides of the front center of the top of the base, a reducer fixedly connected to the rear of one side of the top of the base, and a servo motor fixedly connected to the rear center of the top of the base. A rotating shaft is rotatably connected to the upper center of each support frame on its adjacent side, and a fixing block is fixedly connected to the center of the outer circumference of each rotating shaft. In this utility model, by controlling the second hydraulic cylinder, the limit pin can disengage from the fixing hole. Since the drum is no longer restricted externally, workers can remove the drum for maintenance and repair. After maintenance, workers can control the second hydraulic cylinder again to insert the limit pin into the fixing hole, thus fixing the drum. This facilitates disassembly and maintenance.

[0004] Based on existing solutions and actual production and processing, current automatically lubricated cryogenic winches still have some problems. For example, the drum is limited by parts such as fixed seats, fixed holes, fixed blocks, second hydraulic cylinders, and limit grooves, but the structure is relatively complex and costly. Moreover, the wire rope is prone to wear after long-term use, reducing its lifespan. It is necessary to increase the oil content of the wire rope through lubrication to extend its lifespan. At the same time, the height of the adjusting wheel is adjusted by parts such as two first hydraulic cylinders, limit blocks, guide rods, and slide grooves, but the adjustment structure is relatively complex. Therefore, we propose an automatically lubricated cryogenic winch to solve the problems mentioned above. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-7 This utility model provides a technical solution: an automatically lubricated low-temperature winch, comprising a base plate 1, a first mounting plate 2, a connecting shaft 3, a motor 4, a mounting base 5, a connecting plate 6, a connecting rod 7, a round cover 8, a drum 9, a rotating shaft 10, a second mounting plate 11, an electric telescopic rod 12, a mounting frame 13, an adjusting wheel 14, an oil tank 15, a liquid pump 16, a connecting pipe 17, a hose 18, a connecting cylinder 19, a sponge pad 20, an adjusting plate 21, an adjusting rod 22, and a mounting frame 23.

[0034] Example 1: Existing methods use components such as a fixed seat, fixed hole, fixed block, second hydraulic cylinder, and limiting groove to limit the movement of the drum. However, these methods are complex and costly. Therefore, this example uses the following technical solution: Figure 1 , Figure 3 , Figure 5 and Figure 7Since the limiting structure includes a mounting base 5, a connecting plate 6, a connecting rod 7, a round cover 8, a rotating shaft 10, and a second mounting plate 11, the connecting plate 6 and the hollow structure of the mounting base 5 are nested together with the connecting rod 7. The lower end of the connecting rod 7 is threadedly connected to the round cover 8. The rotating shaft 10 is nested inside the "U"-shaped connection port at the upper end of the second mounting plate 11. Therefore, when replacement is needed, the round cover 8 is rotated to separate it from the connecting rod 7, and the drum 9 is pulled upwards to remove it from the first mounting plate 2 and the second mounting plate 11. Next, place the new drum 9 on the upper side of the first mounting plate 2 and the second mounting plate 11, nest the rotating shaft 10 inside the upper end of the second mounting plate 11, and engage the connecting plate 6 at the upper end of the mounting base 5 so that the hollow structure of the connecting plate 6 is connected to the hollow structure of the mounting base 5. Nest the connecting rod 7 inside the hollow structure of the connecting plate 6 and the mounting base 5, and rotate the round cover 8 so that it is threadedly connected to the lower end of the connecting rod 7 to limit the position of the drum 9, thereby facilitating the disassembly and replacement of the drum 9.

[0035] Example 2: Existing wire ropes are prone to wear and tear after prolonged use, reducing their lifespan. Lubrication is needed to increase the oil content and extend the rope's lifespan. Therefore, this example uses the following technical solution: Figure 1 , Figure 2 and Figure 6 The lubrication structure includes an oil tank 15, a pump 16, a connecting pipe 17, a hose 18, a connecting cylinder 19, a sponge pad 20, an adjusting plate 21, an adjusting rod 22, and a mounting frame 23. The inner end of the connecting cylinder 19 has a porous structure. The front end of the adjusting plate 21 is slidably connected to the inside of the mounting frame 23. The upper and lower ends of the adjusting plate 21 are symmetrically threaded onto the adjusting rod 22. The outer surface of the adjusting rod 22 has a bidirectional threaded structure. The connecting cylinder 19 forms a sliding structure on the upper side of the base plate 1 through the adjusting plate 21 and the adjusting rod 22. The oil tank 15 is connected to the sponge pad 20 through the hose 18 and the connecting cylinder 19. Therefore, the steel wire... When the rope is between the upper and lower sets of connecting cylinders 19, rotate the adjusting rod 22 to make the symmetrically arranged adjusting plates 21 slide inward inside the mounting frame 23, so that the symmetrically arranged connecting cylinders 19 are close to each other until the upper and lower sets of sponge pads 20 are in contact with the wire rope. When the pump 16 is working, the lubricating oil inside the oil tank 15 enters the corresponding connecting cylinder 19 through the connecting pipe 17 and the upper and lower sets of hoses 18. The lubricating oil in the connecting cylinder 19 wets the sponge pad 20 through the porous structure of the inner wall of the drum 9. The lubricating oil on the sponge pad 20 lubricates the wire rope, thus facilitating automatic lubrication of the wire rope.

[0036] Example 3: Existing methods adjust the height of the adjusting wheel using two first hydraulic cylinders, limit blocks, guide rods, slides, and other components. However, the adjustment structure is relatively complex. Therefore, this example uses the following technical solution: Figure 1 , Figure 3 and Figure 4Since the inner end of the mounting frame 13 is rotatably connected to the adjusting wheel 14, and the adjusting wheel 14 is in a lifting structure on the upper side of the base plate 1 through the mounting frame 13, when the motor 4 is working, it drives the connecting shaft 3 to rotate, and through the connecting shaft 3, it drives the drum 9 to rotate on the upper side of the base plate 1 to wind up the wire rope. When the electric telescopic rod 12 is working, it drives the mounting frame 13 to rise and fall, and through the mounting frame 13, it drives the adjusting wheel 14 to move up and down, so that the tension of the wire rope is adjusted when the adjusting wheel 14 rises and falls, thus making it easy to adjust the tension of the wire rope. The adjustment structure is simple. All the electrical components mentioned above are existing technologies and will not be described in detail here.
